Abstract

Compounds having the formula ##STR1## wherein n and m are, individually, 0 or 1, X is an anion, R' is hydrogen, methyl or phenyl and R 2 , R 3 and R 4 are, individually, hydrogen, alkyl, aryl, alkaryl or aralkyl, polymers thereof and methods for their production, are disclosed.

Claims

exact text as granted — not AI-modified
We claim: 
     
       1. A vinyl addition homopolymer of a monomer having the formula ##STR15## wherein n and m are, individually, 0 or 1, X is an anion, R 1  is hydrogen, methyl or phenyl and R 2 , R 3  and R 4  are, individually, hydrogen, alkyl (C 1  -C 4 ), aryl (C 6  -C 10 ), aralkyl (C 7  -C 11 ) or alkaryl (C 7  -C 11 ), being colorless and free of non-amidine imino carboxyl, ester and amide groups, unreacted nitrile groups and unreacted polyamine. 
     
     
       2. A homopolymer according to claim 1 wherein m is 0. 
     
     
       3. A homopolymer according to claim 1 wherein m is 1. 
     
     
       4. A homopolymer according to claim 1 wherein n and m are each 0, and R', R 2 , R 3  and R 4  are each hydrogen. 
     
     
       5. A homopolymer according to claim 1 wherein n is 0, m is 1, and R 1 , R 2 , R 3  and R 4  are each hydrogen. 
     
     
       6. A homopolymer according to claim 1 wherein n and m are each 0, R 1 , R 3  and R 4  are each hydrogen and R 2  is methyl. 
     
     
       7. A homopolymer according to claim 1 wherein n is 0, m is 1, R 1 , R 3  and R 4  are each hydrogen and R 2  is methyl. 
     
     
       8. A homopolymer according to claim 1 wherein n is 1, m is 0 and R 1 , R 2 , R 3  and R 4  are each hydrogen. 
     
     
       9. A homopolymer according to claim 1 wherein n is 1, m is 0, R 1 , R 3  and R 4  are each hydrogen and R 2  is methyl. 
     
     
       10. A homopolymer according to claim 1 wherein n and m are each 1, R 1 , R 3  and R 4  are each hydrogen and R 2  is methyl. 
     
     
       11. A homopolymer according to claim 1 wherein X is sulfate. 
     
     
       12. A homopolymer according to claim 1 wherein X is chloride.
